Book excerpt: The success of duck hunters throughout much of North America each fall depends to a large degree upon the spring productivity of the breeding waterfowl in the northern prairie states and the central provinces of Canada. In southern Manitoba, in the Waterfowl Research Station, a privately endowed outdoor laboratory owned by the North American Wildlife Foundation and operated by the Wildlife Management Institute. Its principal purpose is to determine facts useful in the management and perpetuation of this international migratory resource. When Dr. Lyle K. Sowls began his studies at Delta in 1946, many wide gaps remained in the knowledge of the relationship of breeding ducks to their home range. There were many scattered observations and a growing mass of data accumulated through the study of banding returned; but the activities of individual ducks during the critical spring months and the activities and the fate of broods each summer remained largely a mystery. Sowls, working toward his doctorate in wildlife management as a graduate student of the University of Wisconsin, studied the waterfowl at Delta for five years in an attempt to plug some of those gaps through intensive study of the waterfowl on one limited are. His studies developed new techniques and brought out new facts that were startling even to waterfowl biologists, facts of prime importance to the duck hunter or to any one interest in the future of America’s waterfowl flights. As a result of Dr. Sowls’ research, new light has been shed on such factors as predation, renesting, and homing habits of the important species of game ducks, and already have become the basis for revised hunting regulations and give a new understanding of waterfowl problems.

Book Synopsis A Hundred Years of Texas Waterfowl Hunting by : R. K. Sawyer
Download or read book A Hundred Years of Texas Waterfowl Hunting written by R. K. Sawyer and published by Texas A&M University Press. This book was released on 2012-07-13 with total page 419 pages. Available in PDF, EPUB and Kindle. Book excerpt: The days are gone when seemingly limitless numbers of canvasbacks, mallards, and Canada geese filled the skies above the Texas coast. Gone too are the days when, in a single morning, hunters often harvested ducks, shorebirds, and other waterfowl by the hundreds. The hundred-year period from the mid-nineteenth to the mid-twentieth centuries brought momentous changes in attitudes and game laws: changes initially prompted by sportsmen who witnessed the disappearance of both the birds and their spectacular habitat. These changes forever affected the state’s storied hunting culture. Yet, as R. K. Sawyer discovered, the rich lore and reminiscences of the era’s hunters and guides who plied the marshy haunts from Beaumont to Brownsville, though fading, remain a colorful and essential part of the Texas outdoor heritage. Gleaned from interviews with sportsmen and guides of decades past as well as meticulous research in news archives, Sawyer’s vivid documentation of Texas’ deep-rooted waterfowl hunting tradition is accompanied by a superb collection of historical and modern photographs. He showcases the hunting clubs, the decoys, the duck and goose calls, the equipment, and the unique hunting practices of the period. By preserving this account of a way of life and a coastal environment that have both mostly vanished, A Hundred Years of Texas Waterfowl Hunting also pays tribute to the efforts of all those who fought to ensure that Texas’ waterfowl legacy would endure. This book will aid their efforts, along with those of coastal residents, birders, wildlife biologists, conservationists, and all who are interested in the state’s natural history and in championing the preservation of waterfowl and wetland resources for the benefit of future generations.
Book Synopsis Texas Waterfowl by : William P. Johnson
Download or read book Texas Waterfowl written by William P. Johnson and published by Texas A&M University Press. This book was released on 2013-01-18 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this beautifully illustrated guide, two practicing wildlife biologists describe the life histories of forty-five species of ducks, geese, and swans that occur in Texas. For common species and those that breed in the state, each account begins with an interesting fact (such as, “Red-breasted Mergansers have been clocked at over 80 mph, the fastest recorded flight speed for a duck . . .”) and provides information on Texas distribution and harvest, population status, diet, range and habitats, reproduction, and appearance. Exquisite photographs, informative distribution maps, and a helpful source list accompany the species descriptions, and the book offers a glossary and full bibliography for those who want to explore the literature further. With the degradation and disappearance of the inland and coastal habitats that these birds depend upon, the natural history of these waterfowl species provides a vital reminder of the interconnectedness and crucial importance of all wetlands. Birders, biologists, landowners, hunters, outdoor enthusiasts, and all those interested in the health and preservation of our coastal and inland wetland resources will enjoy and learn from this book.

Book Synopsis Mourning Dove Recoveries from Mexico by : Lytle Houston Blankenship
Download or read book Mourning Dove Recoveries from Mexico written by Lytle Houston Blankenship and published by . This book was released on 1970 with total page 582 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of 37,000 reports of mourning dove band recoveries in the files of the Migratory Bird Populations Station on October 30, 1967, 1,120 came from Mexico, and half of those were from Jalisco and Michoacan, both in west-central Mexico; Jalisco alone accounted for nearly a third. Few recoveries were reported from the area between the U.S. border and mid-Mexico. Generally, lower proportions of total recoveries were reported from Mexico under the current pre-hunting season banding program for flying birds than were reported from the nestling dove banding program of the 1950's. Bandings in the northern U.S. States produced proportionally more recoveries than bandings in the southern U.S. States. Doves banded over diverse areas of the United States were harvested in common migration with wintering areas in Mexico. Possible explanations of the heterogeneous distribution of recoveries throughout Mexico are discussed. Of the banded birds for which "how obtained" was known, 83.5 percent were reported as shot (or killed) and only 3.2 percent reported as captured or trapped. Among 658 persons who gave their name and residence when they reported bands, 95.7 percent had typically Spanish surnames and were residents of Mexico. Depending upon actual banding reporting rates and the representativeness of the banding data analyzed, the Mexican dove harvest may equal or exceed harvests in leading U.S. States. Factors influencing band reporting rates must be resolved before Mexico's importance as a harvest area can be accurately determined.
